POLE SNUBB I NG DEVIC Filed Dec. 24, 1927 3 Sheets-Sheet 3 and: m 4% BY %wa A T/O/CIVE) Patented Mar. 31, 1931 UNITED STATES PATENT OFFICE FRANK H. SCHWERIN, OF BELLEVUE, iPENNSYLVANIA, ASSIGNOR TO THE DUFF-NOR- TON MANUFACTURING CQMPANY, OF PITTSBURGH, PENNSYLVANIA, A. CORPORA- TION OF PENNSYLVANIA V POLE-SNUBBING DEVICE Application filed December 24, 1927. Serial No. 242,492.

The object of the invention is to provide a simple strong, convenient and effective screw device for use in pole snubbing or the binding of poles together. A further object L is to provide a device of this character which is adapted to be supported and kept in position projecting horizontally from a pole without manual or extraneous support.

The device comprises an elongated frame having a base adapted to fit the curvature of a pole and provided with a suspension bracket, a screw shaft rotatably mounted at its opposite ends in the frame, operating means connected with the outer end of said shaft. :1 nonrotary nut traveler on the screw shaft, a yoke having arms projecting oppositely from the nut traveler through longitudinal slots in the sides of the frame, and hooks on the ends of said arms to receive gripsholding the ends of a cable which is passed about the poles. These and other features of the invention will become apparent as the specification proceeds, and will be more particularly pointed out in the claims.

In the accompanying drawings, forming part hereof:

Fig. 1 is a longitudinal section through the device, with parts in elevation;

Fig. 2 is a cross-section on the line 2-2 of Fig. 1' Fig. 3 is an elevation of approximately the inner half of the device, the remainder being broken away, this view looking at right angles to Fig. 1; and

Fig. 4 is a plan view of the device in use, showing the cable passing about two poles, which are represented in section, and grips and clamps which are used in connection with the operation.

The work for which the device is more particularly designed is the drawing and binding together of two poles, or one pole to another pole already standing in the ground.

The device comprises a strong, hollow, elongated frame 2 of approximately square section. At one end this frame has an intcgral enlarged base 3, which is arched and generally incurved at the under side so as to conform to the side of a pole, when applied thereto, as illustrated in Fig. 4. The base is strengthened beneath by ribs 4 and 5 running in two directions, the ribs5 and the edges 6 of the base at the ends of the curve projecting somewhat so as to form a number of points or lines of contact with the side of the pole.

a The sides of the base terminating in the edges 6 have central notches 7 formedtherein for a purpose which will appear. One of the edges of the base has a projecting flange 8 formed with a key-hole opening 9, the purpose of which, also, will appear. Two opposite sides of the frame have longitudinal slots 10 extending from theouter end portion of the frame to pointsadjacent the base, where they communicate with enlarged openings 11 in the same sides.

In the center of the base there is a bearing opening 12, and in the outer end of the frame there is another bearing opening 13. A screw-shaft 14: has unthreaded journal portions 15 and 16 at the opposite ends of its screw-threaded portion. This shaft is inserted into theframe through the opening 13, itsjournal portion 15engaging the bearing 12 and its journal portion 16 occupying the opening 13. A cotter pin 17 passed through a transverse opening in the shaft inwardl of the outer endof the frame holds the screw against coming out. The portion of the shaft which projects outwardly of the end of the frame is provided with ahead 18, between which and the frame there is a thrust-bearing preferably comprising washers 19. A handle rod 20 is passed through a cross opening in the headof the screw for operation.

A traveler nut 21 is disposed within the frame on the screw 14 this nut having a flange 22 atits innerend. A yoke 23 is formed. with a central. portion 24 fitting the nut and with oppositely extending arms 25, which latter project outwardthrough the slots 10 to a distance at each side of the frame. The central portion 24 of the yoke has an opening whereby it fits around the nut and against the flange 22, and the nut and yoke are united together by pins 26. The said central portion of the yoke is approximately rectangular in form, substantially filling thecross-section of the interior of the frame, wherein it is non-rotatably guided, the nut being also held from turning by reason of being united to the yoke. The outer ends of the arms 25 are formed with hooks 27, provided with spring-pressed snap pins 28.

In assembling the device, the yoke and nut are adapted to be introduced into thermm'e through the enlarged openings 11, a after which the screw is inserted through the outer end of the frame and screwed through the nut into its proper position in the frame. 7

A mode of using the device is illustrated in Fig. 4:, wherein 30 may bea standing pole and is passedtwicearound the two poles, with its ends 33 at the same side ofthe pole 31. A nail 34 is driven into the pole 31 and the device is hung from this nail by means'of the eyelet flange8. The notches7inthe edges 6 of the base of the flange enable the base to straddle the courses of the cable which pass about the outer side of the pole 31. A pair of wiregrips 35 are, applied tothe hook ends of the arms 25. These grips are known devices for gripping wire and need not be particularly illustrated. ,They may remain connected with the arms, and held against unintended disconnectionby the snaps 28. "The ends of the cable are inserted in the grips, and the handle 20 is then operated to turn the screw shaft and draw'the yoke away from the pole. By this action the cable is ,pulled tight around the poles, and the pole 31' is forced close against the pole 30. WVhen this has beenaccomplished clamps 36 are afiixed to'the two icourses of the cable at oppositesides of the'pole,completing the fastening. The grips-35 arethen disengaged from the :ends of the cable, and theexcess cable ends may be cut ofi.

The device requires no supporter holding, manual or otherwise, other than the engagement of the eyelet bracket with the nail outerportion of said shaft. I
